The thermal plastics added with long glass fiber composite is one kind of highly functional composite material, with good tenacity, high strength, low density, and excellent anti-erosion and heat-resistant properties, comparable to the aluminum/magnesium alloy.Moreover, it’s easy to shape, durable, and recyclable, serving as one kind of low energy-consuming and pollution-free green materials. Compared to other materials to be used for the main structure, it’s similar in mechanical strength while its weight can be reduced by over 80%, widely applied to automobile, construction, chemical, packaging, electricity, and transportation sectors.
